...And you say, "Oh, well that's a really weak etymological connection."
Do you think so? You might want to check every occurence of the word "Sheol" in the Hebrew text and see how it correlates with the concept of gravity.

I don't know, what is it, like 40 occurences, maybe more, and most of them refer to down to the grave, and only once, I think, is the preposition up (isn't that a preposition?) used?

Indeed. In fact, too interesting for your own beliefs' good (certainly for said beliefs' continued existence, from your point of view, minorityob). So the Bible = a yaoi (as in 'BL': Boy Love) manga/light novel/anime, hmmmmmmmm?!:

But then, Jesus hung around with twelve men (two of whom were sailors), hardly associated with women - if ever, was kissed by a man (Judas), never got married, and wore a dress. Ending up in a storyline known as 'The Passion'.

You said it, I didn't.

>:D

Moral: Be careful what analogy you use. It may well bite you in the anal area.

An Atheist with a Bible is a Dangerous Thing indeed (emphasis added):

'Know your enemy and know yourself, and you will not be imperiled in a hundred battles.'

Because the Hebrew writers knew that the Englih word for 'sheol' kinda sounded like the Latin one for 'heavy'.

And for the etymology: grave is related to Dutch (and possibly German) graven, to dig, which comes from Proto-Indo-European g?rab?.
Gravity comes from Latin gravis, heavy, which comes from PIE g?réh2us.
That is so weak, it's nonexistent.

Note that PIE has nothing to do with Hebrew, which is a Semitic language, unrelated to English.

Using Google Translate gave me two very different words (apparently it doesn't work to copy/paste them here), one with 7 or 8 letters, the other with tree, none (or perhaps one) of which looked similar.
I fail to see the connection , but I neither read nor speak Hebrew...
